4.2 I/O Config
NOTE
When GPIB Controller is enabled, the analyzer application itself cannot be
controlled over GPIB. In this case, it can be controlled via LAN or USB. The
GPIB port cannot be a Controller and Device at the same time. Only one
Controller can be active on the GPIB bus at any given time. If the instrument is
the Controller, an external PC cannot also be a Controller.
To control the instrument from the software that is performing GPIB Controller
operation, you can use an internal TCP/IP connection to the analyzer application.
Use the following IP Address to send commands to the analyzer application:
TCPIP0:localhost:inst0:INSTR
Remote
Command
:SYSTem:COMMunicate:GPIB[1][:SELF]:CONTroller[:ENABle] ON | OFF | 0 | 1
:SYSTem:COMMunicate:GPIB[1][:SELF]:CONTroller[:ENABle]?
Example Set GPIB port to Controller:
:SYST:COMM:GPIB:CONT ON
Set GPIB port to Device:
:SYST:COMM:GPIB:CONT OFF
Notes When the instrument becomes the Controller, Bit 0 in the Standard Event Status Register is set. When
the instrument relinquishes Controller capability, bit 0 is cleared
Preset Unaffected by Preset, but set to OFF (Disabled) by Restore Defaults >"Misc" on page 1798
State Saved No
Range Disabled | Enabled
4.2.2 SCPI LAN
Displays a menu for identifying and changing SCPI over a LAN configuration. There
are several ways to send SCPI remote commands to the instrument over LAN.
Having multiple users simultaneously accessing the instrument over the LAN may
lead to communication problems. These controls can help to prevent that, by
disabling the telnet, socket, and/or SICL capability.
NOTE
When multiple instances of the application are running, Telnet port 5023, socket
port 5025, SICL server inst0 and HiSLIP server Device 0 will be assigned to the
first instance; Telnet port 5123, socket port 5125, SICL server inst1 and HiSLIP
server Device 1 will be assigned to the second instance; Telnet port 5223, socket
port 5225, SICL server inst2 and HiSLIP server Device 2 will be assigned to the
third instance; Telnet port 5323, socket port 5325, SICL server inst3 and HiSLIP
server Device 3 will be assigned to the fourth instance.
